none are legitimate.
however some do payout, in the hope you return and pay in more for a second chance.. which they then rob you
my favourite 3 rules:
1. if its too good to be true. then its no good at all.
2. unless you know enough about them to physically slap them with a wet fish should they do you wrong, dont pay them
3. if your still going to risk it and you dont know them enough to get returns.. then you deserve to slap yourself with a wet fish, and dont cry when ur hit
